       2. The mobile terminal of  claim 1 , wherein the interactive service is performed on the IPTV server and the information corresponding to the interactive service is received by the IPTV terminal via an Internet communication connection between the IPTV related server and the IPTV terminal. 
     
     
       3. The mobile terminal of  claim 2 , wherein the IPTV terminal transmits the information corresponding to the interactive service to the mobile terminal via a short range wireless communication method different than the Internet communication connection between the IPTV related server and the IPTV terminal, and
 wherein the control unit is further configured to control the wireless communication unit to receive the information corresponding to the interactive service from the IPTV terminal and to control the output unit to output the received information corresponding to the interactive service. 
 
     
     
       4. The mobile terminal of  claim 3 , wherein the predetermined distance is an available distance for the short-range wireless communication with the IPTV terminal. 
     
     
       5. The mobile terminal of  claim 1 , wherein the received participation information for the interactive service output on the output unit includes at least one of a) a selectable option indicating a user of the mobile does want to participate in the interactive service, b) detailed information about the interactive service and c) a broadcast organization information including a plurality of broadcast programs and iconic information indicating whether a corresponding broadcast program includes the interactive service. 
     
     
       6. The mobile terminal of  claim 1 , wherein the control unit is further configured to control the output unit to output options for allowing a user of the mobile terminal to instruct when the output unit is to output the information corresponding to the interactive service. 
     
     
       7. The mobile terminal of  claim 1 , wherein the controller is further configured to control the output unit to output the received participation information after a lapse of a predetermined time. 
     
     
       8. A method of controlling a mobile terminal, the method comprising:
 wirelessly communicating, via a wireless communication unit, with an Internet Protocol Television (IPTV) terminal and receiving participation information for participating in an interactive service from the IPTV terminal; 
 outputting, via an output unit, the received participation information for the interactive service; 
 receiving, via a user input unit, an input of response information corresponding to the output participation information for the interactive service; 
 transmitting, via a control unit controlling the wireless communication unit, the input response information to the IPTV terminal or to a related IPTV server performing the interactive service with the IPTV terminal; 
 receiving, via the wireless communication unit, information corresponding to the interactive service; 
 receiving, via the input unit, a designated signal indicating a specific place or location of the mobile terminal where the user wants to participate in the interactive service; and 
 transmitting, via the wireless communication unit, a notification signal to the IPTV terminal for receiving the participation information in response to the notification signal, when the mobile terminal is located at the specific place or location, 
 wherein the wireless communication unit further receives the participation information, when the mobile terminal is within a predetermined distance from the IPTV terminal. 
 
     
     
       9. The method of  claim 8 , wherein the interactive service is performed on the IPTV server and the information corresponding to the interactive service is received by the IPTV terminal via an Internet communication connection between the IPTV related server and the IPTV terminal. 
     
     
       10. The method of  claim 9 , wherein the IPTV terminal transmits the information corresponding to the interactive service to the mobile terminal via a short range wireless communication method different than the Internet communication connection between the IPTV related server and the IPTV terminal, and
 wherein the method further comprises receiving, via the wireless communication unit, the information corresponding to the interactive service from the IPTV terminal and outputting, via the output unit, the received information corresponding to the interactive service. 
 
     
     
       11. The method of  claim 10 , wherein the predetermined distance is an available distance for the short-range wireless communication with the IPTV terminal. 
     
     
       12. The method of  claim 8 , wherein the output participation information for the interactive service includes at least one of a) a selectable option indicating a user of the mobile does want to participate in the interactive service, b) detailed information about the interactive service and c) a broadcast organization information including a plurality of broadcast programs and iconic information indicating whether a corresponding broadcast program includes the interactive service. 
     
     
       13. The method of  claim 8 , further comprising:
 outputting, via the output unit, options for allowing a user of the mobile terminal to instruct when the output unit is to output the information corresponding to the interactive service.
